General Mach Discussion / Re: Max output current from a single Parallel port pin?

« on: September 19, 2012, 01:45:29 AM »

Hi Sweep,

Obviously not all parallel ports are produced to the same specification but the maximum value that can safely be drawn from any one pin should be considered as not to exceed 10mA (the port is primarily designed to sink current rather than source it).

Just as a tip, it would be far better to use a USB port for the source of the 5 Volts supply in your circuit (or else use a separate 5 Volt supply).

Hi Ansen,

Welcome to the forum.

I find your photography method most interesting and the results are indeed quite spectacular.
I look forward to seeing some of your innovative CNC work.

Hi Johnny,

Welcome to the forum.

The S*** command works OK in demo mode.
If you post your question in the General section someone will be along to help.

Hi Jammer,

Another brilliant idea. 

I do admire your casting work.

Hi George,

In the Diagnostics screen, try turning off Toolpath (bottom left).

General Mach Discussion / Re: Another Tangential Knife problem.

Thanks Terry, leads are something I had not considered - I will see how it goes.

(changing the +Z moves to a G01 make no difference - the A rotation is still blended with the +Z move)

General Mach Discussion / Another Tangential Knife problem.

« on: September 07, 2012, 06:20:31 AM »

When cutting a rectangle, the knife is rotated to the direction of the first cut (A Axis), lowered into the work (Z Axis) and at the end of the line the knife is retracted from the work, rotated to the direction of the next cut, lowered into the work and so on. Nothing wrong here and everything works just as it should.

When cutting many circles it is an entirely different situation. After completing the first circle the knife rotates to the start direction of the next circle as a blended move with the Z Axis retracting the knife (the knife rotates within the work whilst being withdrawn).

I can overcome this problem by creating a tool path where each circle starts and finishes in exactly the same direction (and not optimizing the tool path for shortest route) but is there an easier solution please ??
